What are you referring to with "there"?
I mean in the situation where BlackHatCoiner was talking about.
I am a bit lost, because I don't know what specifically he is talking about in 2020 except as a 6 year reference before 2026. I thought that you were talking about something very specific or personal with your reference to 2020, because anyone who is still alive and is at least 6 years old was there.

Such a strong emotion will surely motivate you. It’s what makes the world round after all. But make sure you place your anger towards the right things to be productive and not spread negativity.
Weak minded people tend to confuse reality for negativity, and this is because they have issues accepting that the world is all messed up. The parties that they are voting for are corrupt, in most cases the religion that they are part of is a scam, many of their family members and friends are dishonest people and criminals, and so forth. Weaklings have an issue with these things, that is why they label things: negativity, racism, Islamophobia, sexism, Nazism, fascism, whatever other bullshit they can come up with. Negativity would be being upset and angry at something normal, mundane, like daily car traffic. However,
being angry at a system that is objectively broken and corrupt is realism. These days I am still undecided as to who creates more damage in democracy as a group, those that reject reality (as I have described) or those that are completely apathetic to anything that is important. Both of these types of people are a disease, they are dangerous to everyone else and the planet. Democracy has failed.
At this point, you will be overwhelmed by emotions, And you don't have 2 decisions, you have a couple of decisions to make.
Wrong. Don't generalize people based on stereotypes of people with low intelligence and low inhibitions. It is perfectly possible to have a burning fire inside of any kind of emotion, and still not act on it for whatever reason. A person may hate you deeply and they may even feel that they want to kill you, but what separates normal people from violent animals is that they have proper inhibitions in place and they will not act on something that is wrong -- like killing you would be. It is pretty easy not to get overwhelmed by any emotion, but you need to learn this skill.
So there is always another chance to start making the right decisions again
Incorrect, there is no second chance. The time that you have messed up is gone, there is no bringing it back. Accept that you fucked up, and get rid of these coping mechanism. Changing yourself today is not having a "another chance" at something, it is a new start with the time that is remaining (which is reduced either by a little or by a lot depending on how long it took you to get your act together).
